Difusor de sustancias volátiles por combustiónCombustion volatile substance diffuser
La presente invención se refiere a un difusor de sustancias volátiles por combustión, en particular, a un difusor en forma de espiral para ahuyentar insectos, por ejemplo, mosquitos, o a un difusor que se utiliza como ambientador.The present invention relates to a diffuser of volatile substances by combustion, in particular, to a diffuser in the form of a spiral to drive away insects, for example, mosquitoes, or to a diffuser that is used as an air freshener.
Antecedentes de la invenciónBackground of the Invention
Las espirales para mosquitos que se utilizan como insecticidas son conocidas desde hace años. A pesar de eso, siguen siendo un producto muy utilizado, especialmente para aplicaciones externas.Mosquito coils that are used as insecticides have been known for years. Despite that, they are still a widely used product, especially for external applications.
Generalmente consisten en una mezcla de partículas de madera que se extruden en un estado húmedo junto con el ingrediente activo volátil y generalmente también con algún aditivo para controlar la combustión sin llama. Después del proceso de extrusión, el perfil extrudido se expone a un proceso de acabado de conformación y luego se seca para obtener un producto sólido.They generally consist of a mixture of wood particles that are extruded in a wet state together with the volatile active ingredient and generally also with some additive to control the combustion without flame. After the extrusion process, the extruded profile is exposed to a forming finishing process and then dried to obtain a solid product.
El proceso de secado es un proceso bastante sensible y crítico. Una temperatura excesiva durante el secado podría provocar la evaporación de parte del ingrediente activo, reduciendo la eficiencia futura de la espiral, y también con una pérdida de dinero, ya que el ingrediente activo suele ser considerablemente más caro que el otro componente de la mezcla.The drying process is a fairly sensitive and critical process. Excessive temperature during drying could cause evaporation of part of the active ingredient, reducing the future efficiency of the coil, and also with a loss of money, since the active ingredient is usually considerably more expensive than the other component of the mixture.
Además de eso, el contenido final del ingrediente activo es de gran importancia, ya que este valor suele estar indicado en el registro sanitario para productos biocidas con una cierta tolerancia permitida, y quedar fuera de esta tolerancia puede llevar a la retirada del producto del mercado.In addition to that, the final content of the active ingredient is of great importance, since this value is usually indicated in the sanitary registry for biocidal products with a certain permitted tolerance, and being outside this tolerance may lead to the withdrawal of the product from the market. .
Por lo tanto, generalmente el secado se realiza durante un período de tiempo bastante largo, más cercano a días que a horas, con una temperatura bastante baja de 40-80 °C para evitar la evaporación de los ingredientes activos de insecticidas estándar, que suelen tener una baja volatilidad.Therefore, drying is generally carried out for a fairly long period of time, closer to days than hours, with a low enough temperature of 40-80 ° C to avoid evaporation of the active ingredients of standard insecticides, which are usually have low volatility.
La industria de ingredientes activos de insecticidas ha estado trabajando a lo largo de las últimas décadas para obtener nuevas moléculas de ingredientes activos que tengan una menor toxicidad, una mayor eficiencia y también una mayor volatilidad.The insecticide active ingredient industry has been working throughout the last decades to obtain new molecules of active ingredients that have less toxicity, greater efficiency and also greater volatility.
El proceso actual de fabricación de espirales para mosquitos que implica la extrusión en húmedo y el posterior secado se vuelve completamente inadecuado para esta nueva generación de insecticidas, ya que se evaporan significativamente a la temperatura utilizada durante el secado.The current mosquito coil manufacturing process involving wet extrusion and subsequent drying becomes completely unsuitable for this new generation of insecticides, as they evaporate significantly at the temperature used during drying.
Por otro lado, la microencapsulación es un proceso bastante conocido y su uso para reducir la evaporación de sustancias de alta volatilidad es bastante común. Un ejemplo típico es la fragancia microencapsulada que se rompe mecánicamente, que es una cápsula en la que una membrana rodea una gota de fragancia y evita su liberación siempre que el usuario no la rompa aplicando una presión sobre la misma.On the other hand, microencapsulation is a fairly well-known process and its use to reduce the evaporation of high volatility substances is quite common. A typical example is the mechanically-ruptured microencapsulated fragrance, which is a capsule in which a membrane surrounds a drop of fragrance and prevents its release as long as the user does not break it by applying pressure to it.
La aplicación típica son las etiquetas para raspar y oler, para permitir al usuario oler el producto antes de comprarlo, detergentes y suavizantes, para un efecto duradero de la fragancia en el tejido, etc. Para estas aplicaciones, el tipo más común de microcápsulas utilizadas se basa en una membrana de melamina.The typical application is the scratch and smell labels, to allow the user to smell the product before buying it, detergents and softeners, for a lasting effect of the fragrance on the fabric, etc. For these applications, the most common type of microcapsules used is based on a melamine membrane.
Este tipo de cápsulas podrían satisfacer la necesidad de evitar la pérdida de ingredientes activos durante el secado, pero apenas sobrevivirían a la tensión mecánica generada durante un proceso de extrusión.These types of capsules could satisfy the need to avoid the loss of active ingredients during drying, but they would hardly survive the mechanical stress generated during an extrusion process.
Por lo tanto, un objetivo de la presente invención es proporcionar un difusor de sustancias volátiles por combustión en el que se reduzca o evite completamente la evaporación de las sustancias volátiles durante su secado en su proceso de fabricación.Therefore, an object of the present invention is to provide a combustion volatile substance diffuser in which evaporation of volatile substances is reduced or completely prevented during drying in its manufacturing process.
Descripción de la invenciónDescription of the Invention
Con el difusor de la invención se consiguen resolver los inconvenientes citados, presentando otras ventajas que se describirán a continuación.With the diffuser of the invention it is possible to solve the aforementioned drawbacks, presenting other advantages that will be described below.
El difusor de sustancias volátiles por combustión de acuerdo con la presente invención comprende un cuerpo que incluye dichas sustancias volátiles, en el que dicho cuerpo está formado a partir de microcápsulas que integran dichas sustancias volátiles. The combustion volatile substance diffuser according to the present invention comprises a body including said volatile substances, in which said body is formed from microcapsules that integrate said volatile substances.
Ventajosamente, cada microcápsula comprende una carcasa exterior que aloja en su interior las sustancias volátiles, en el que la carcasa exterior puede hacerse de un material polimérico, y/o se elige entre el grupo de goma arábiga, goma de xantano, ácidos grasos, alcoholes grasos, ceras naturales y polietileno.Advantageously, each microcapsule comprises an outer shell that houses the volatile substances inside, in which the outer shell can be made of a polymeric material, and / or is chosen from the group of gum arabic, xanthan gum, fatty acids, alcohols fatty, natural waxes and polyethylene.
Además, dicha carcasa exterior está hecha de un material que se activa térmicamente, de manera que se funde, expande o colapsa al estar por encima de una temperatura predeterminada, difundiendo las sustancias volátiles al entorno. Por ejemplo, dicha carcasa exterior se activa térmicamente a una temperatura comprendida entre 80 °C y 150 °C.Furthermore, said outer shell is made of a material that is thermally activated, so that it melts, expands or collapses when it is above a predetermined temperature, spreading the volatile substances to the environment. For example, said outer shell is thermally activated at a temperature between 80 ° C and 150 ° C.
Preferentemente, dicha carcasa exterior aloja en su interior, junto con las sustancias activas, serrín, productos de ayuda a la combustión, antioxidantes y/o agentes antihongos, aunque también podría alojar componentes convencionales de este tipo de difusores de sustancias volátiles por combustión.Preferably, said outer shell houses, together with the active substances, sawdust, combustion aids, antioxidants and / or antifungal agents, although it could also house conventional components of this type of diffusers of volatile substances by combustion.
De acuerdo con una realización preferida, dicho serrín tiene un tamaño de partícula comprendido entre 0,1 y 1 mm, los productos de ayuda a la combustión se eligen del grupo que comprende nitrato de sodio, nitrato de potasio y benzoato de sodio, y dichas sustancias volátiles se eligen del grupo que comprende piretroides, geraniol y/o citronela.According to a preferred embodiment, said sawdust has a particle size between 0.1 and 1 mm, the combustion aid products are chosen from the group comprising sodium nitrate, potassium nitrate and sodium benzoate, and said Volatile substances are chosen from the group comprising pyrethroids, geraniol and / or citronella.
De acuerdo con una realización preferida, dicho cuerpo tiene una forma en espiral.According to a preferred embodiment, said body has a spiral shape.
Por lo tanto, en el difusor de la presente invención, tal como, por ejemplo, una espiral para mosquitos, las sustancias volátiles no se agregan como un líquido, sino que se integran en microcápsulas, y dichas microcápsulas reducen o evitan por completo la evaporación del ingrediente activo durante el secado.Therefore, in the diffuser of the present invention, such as, for example, a mosquito coil, the volatile substances are not added as a liquid, but are integrated into microcapsules, and such microcapsules reduce or completely prevent evaporation. of the active ingredient during drying.
Breve descripción de los dibujosBrief description of the drawings
Para mejor comprensión de cuanto se ha expuesto, se acompañan unos dibujos en los que, esquemáticamente y tan sólo a título de ejemplo no limitativo, se representa un caso práctico de realización.For a better understanding of what has been stated, some drawings are attached in which, schematically and only by way of non-limiting example, a practical case of embodiment is represented.
La figura 1 es una vista en perspectiva de un difusor de sustancias volátiles por combustión de acuerdo con una realización de la presente invención, donde se han representado las microcápsulas en una porción del mismo. Fig. 1 is a perspective view of a volatile combustion diffuser in accordance with an embodiment of the present invention, wherein the microcapsules have been depicted in a portion thereof.
Descripción de una realización preferidaDescription of a preferred embodiment
Tal como se muestra en la figura 1, el difusor de sustancias volátiles por combustión de acuerdo con la presente invención comprende un cuerpo 1, por ejemplo, en forma de espiral de acuerdo con la realización representada que incluye las sustancias volátiles a difundir en el entorno, pudiendo ser dichas sustancias volátiles insecticidas para repeler insectos o aromáticas para perfumar el entorno.As shown in Fig. 1, the combustion volatile substance diffuser according to the present invention comprises a body 1, for example spiral-shaped according to the illustrated embodiment which includes the volatile substances to diffuse into the environment , said volatile substances being insecticidal to repel insects or aromatic to perfume the environment.
De acuerdo con la presente invención, el cuerpo 1 está formado a partir de microcápsulas 2 que alojan en su interior las sustancias volátiles, en particular, mediante una carcasa externa polimérica.According to the present invention, the body 1 is formed from microcapsules 2 that house the volatile substances inside, in particular, by means of a polymeric external casing.
Para su uso, dicho cuerpo 1 se quema, produciendo la rotura de la carcasa externa de las microcápsulas 1 por temperatura y difundiendo las sustancias volátiles al entorno.For use, said body 1 burns, causing the external casing of the microcapsules 1 to break due to temperature and spreading the volatile substances to the environment.
Por lo tanto, el tipo de microcápsulas de interés para la presente invención son las microcápsulas que se activan por la temperatura, es decir, se rompen al superar una temperatura predeterminada, no las que se activan o rompen mecánicamente por fricción, como en las microcápsulas convencionales.Therefore, the type of microcapsules of interest for the present invention are microcapsules that are activated by temperature, that is, they break when they exceed a predetermined temperature, not those that are mechanically activated or break by friction, as in microcapsules. conventional.
La activación se puede lograr a través de dos mecanismos diferentes: liberación sensible a la temperatura, donde los materiales de la carcasa se expanden o colapsan a una temperatura crítica específica, y liberación activada por fusión, donde el material de la carcasa se funde debido al aumento de la temperatura.Activation can be achieved through two different mechanisms: temperature-sensitive release, where the shell materials expand or collapse at a specific critical temperature, and fusion-activated release, where the shell material melts due to temperature increase.
Los materiales de carcasa con tales propiedades pueden ser (sin limitación) goma arábiga, goma de xantano, ácidos grasos, alcohol graso, ceras naturales, polietileno, etc.Carcass materials with such properties can be (without limitation) gum arabic, xanthan gum, fatty acids, fatty alcohol, natural waxes, polyethylene, etc.
Por lo tanto, la carcasa polimérica protegerá las sustancias volátiles y evitará su evaporación durante el secado, y se romperá o fundirá cuando se exponga al calor de la combustión y liberará las sustancias volátiles a la atmósfera.Therefore, the polymeric shell will protect the volatile substances and prevent their evaporation during drying, and will break or melt when exposed to the heat of combustion and release the volatile substances into the atmosphere.
Aunque los mecanismos de activación de las microcápsulas son bastante rápidos, el aumento de temperatura cuando el frente de combustión se está acercando a las microcápsulas puede ser igualmente bueno. Although the activation mechanisms of the microcapsules are quite rapid, the increase in temperature when the combustion front is approaching the microcapsules can be equally good.
En consecuencia, es crítico que la sustancia volátil se libere lo suficientemente rápido para evitar que su integridad química se vea afectada por la temperatura.Consequently, it is critical that the volatile substance be released quickly enough to prevent its chemical integrity from being affected by temperature.
Por lo tanto, es preferible que la activación térmica de las microcápsulas se encuentre en el intervalo de temperatura de 80 °C a 150 °C.Therefore, it is preferable that the thermal activation of the microcapsules is in the temperature range of 80 ° C to 150 ° C.
En cuanto a la composición del contenido de las microcápsulas, estas comprenden:Regarding the composition of the content of the microcapsules, they include:
- serrín de madera con un tamaño de partícula de 0,1 a 1 mm,- wood sawdust with a particle size of 0.1 to 1 mm,
- sustancias volátiles es el intervalo de un 0,05 % a un 5 % en peso (0,05 % considerando piretroides de alta eficiencia de última generación), 5 % considerando insecticidas de bajo rendimiento como geraniol o citronela,- volatile substances is the range from 0.05% to 5% by weight (0.05% considering last generation high-efficiency pyrethroids), 5% considering low-performance insecticides such as geraniol or citronella,
- productos de ayuda a la combustión entre un 0,2 % y un 1% en peso (los productos de ayuda a la combustión pueden ser nitrato de sodio, nitrato de potasio, benzoato de sodio o cualquier otro material comúnmente utilizado como ayuda a la combustión),- combustion aid products between 0.2% and 1% by weight (combustion aid products can be sodium nitrate, potassium nitrate, sodium benzoate or any other material commonly used as an aid to combustion. combustion),
- antioxidantes, y- antioxidants, and
- agentes antihongos.- antifungal agents.
Ventajosamente, se añadirán las microcápsulas antes de la extrusión como una suspensión. La suspensión es una suspensión de microcápsulas en agua, generalmente con una concentración máxima de microcápsulas de aproximadamente el 50 %.Advantageously, the microcapsules will be added before extrusion as a suspension. The suspension is a suspension of microcapsules in water, generally with a maximum microcapsule concentration of approximately 50%.
Como se explicó anteriormente, para la extrusión del cuerpo del difusor, se agrega agua a la mezcla de madera más aditivos. Por lo tanto, si se usa una suspensión, el porcentaje de microcápsulas será aproximadamente igual al porcentaje equivalente sin las microcápsulas, pero eliminaremos de la cantidad de valor añadido el equivalente del agua en la suspensión.As explained above, for the extrusion of the diffuser body, more additives are added to the wood mix. Therefore, if a suspension is used, the percentage of microcapsules will be approximately equal to the equivalent percentage without the microcapsules, but we will remove from the amount of value added the equivalent of the water in the suspension.
A pesar de que se ha hecho referencia a una realización concreta de la invención, es evidente para un experto en la materia que el difusor descrito es susceptible de numerosas variaciones y modificaciones, y que todos los detalles mencionados pueden ser sustituidos por otros técnicamente equivalentes, sin apartarse del ámbito de protección definido por las reivindicaciones adjuntas. Although reference has been made to a specific embodiment of the invention, it is evident to a person skilled in the art that the described diffuser is susceptible of numerous variations and modifications, and that all the mentioned details can be replaced by other technically equivalent ones, without departing from the scope of protection defined by the appended claims.
